The PRC-77 is a manpack portable VHF-FM combat transceiver used to provide short range two way radio telephone voice communication. Used extensively during the Vietnam War starting in 1968, the PRC-77 went out of service in the 1980's. Used by over 17 militaries throughout the world, transmitting range was approximately 5 miles. This set is complete with whip antenna, hard antenna, field phone, manuals and extra battery. I have not operated this set but it is in very good condition so may work if battery was charged. Frequency Ranges: Low Band 30-53MHz  High Band: 53-75.95 MHz.
